Located along the main axis of the Quartier Nord in Brussels, this project includes two sister towers that develop on 62.000 m². In direct connection with the public space, the 2-storey podium hosts, the main entrances, the foyer of a conference room, a shop, cafeterias and lounges. This project offers an integrated urban architecture with real sculptural elegance while being optimal from an ecological point of view. The techniques used for the façades are a Single Skin Unitized Curtain Walling for the main flat surfaces, Double Skin Unitized Curtain Walling for the curved surfaces, Stick Curtain Walling for the ground level and Aluminium Rainscreen for the canopy.
